WebThe gray curve on the left side is the standard normal curve, which always has mean = 0 and standard deviation = 1. We work out the probability of an event by first working out the z-scores (which refer to the distance from the mean in the standard normal curve) using the formulas shown. WebAs a probability distribution, the area under this curve is defined to be one. A normal distribution of mean 50 and width 10. The horizontal axis is the random variable (your measurement) and the vertical is the probability density. The normal distribution is characterized by two numbers μ and σ. The symbol μ represents the the central location.
